This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
var | |
// Local ip address that we're trying to calculate | |
address | |
// Provides a few basic operating-system related utility functions (built-in) | |
,os = require('os') | |
// Network interfaces | |
,ifaces = os.networkInterfaces(); | |
// Iterate over interfaces ... |
function retry(isDone, next) { | |
var current_trial = 0, max_retry = 50, interval = 10, is_timeout = false; | |
var id = window.setInterval( | |
function() { | |
if (isDone()) { | |
window.clearInterval(id); | |
next(is_timeout); | |
} | |
if (current_trial++ > max_retry) { | |
window.clearInterval(id); |
// set-up a connection between the client and the server | |
var socket = io.connect(); | |
// let's assume that the client page, once rendered, knows what room it wants to join | |
var room = "abc123"; | |
socket.on('connect', function() { | |
// Connected, let's sign-up for to receive messages for this room | |
socket.emit('room', room); | |
}); |
